The email from Agent@Adobe.com claims to be from Adobe. After analyzing its source i have not found anything suspicious, only ivest8 and this IP: 98.143.35.69.
While invest8 shows a lot in Google, i have analyzed IP:

When i followed link, i have arrived to a page trying me to peddle something so it was obvious email was not real.
It also is weird that after i saved email as .HTML file and executed it, i was brought to site without being able to view email. Looks like a tricky redirect in source code to me...
If anybody here knows how to find forged and spoofy emails, can you enlighten me please? Here is the link to download .EML file.
Thanks.
